St Pauli game on Monday referee awarded a penalty, the video assistant referee suggested the referee go take a look at the video and he accepted he got it wrong and overturned it. There was also a big mass confrontation of players at the end, he did the normal ref business of booking the two players first involved, then had it highlighted to him that what started it was worth taking another look at, he did, it was, red card. Used twice in the game other than checking goals and was spot on. It's like that every game I watch if they do have to use it.
I should say that it's not perfect because humans use it but it seems to be used like it's in a different universe to the EPL.
